I recall that these were data overflow errors, and were caused by a
radar of some sort mistakenly being left on.  Apparently the program did
OK, discarding the data it couldn't process quickly enough.  I don't
recall if the crew took any action other than "ignore it--press on".  It
turned out that Eagle landed around 4 miles farther downrange than
intended--I also don't know if this error had anything to do with that.
In the end, Armstrong took manual control when he saw the automatic
pilot was heading Eagle for a field strewn with large rocks.  There were
anxious moments on the ground when they saw Eagle's forward speed
increase to around 60 mph to cross the boulder field.  On the tapes you
can hear the ground reminding Eagle that they have only 60, then 30
seconds of fuel left.  When Eagle finally touched down, there was under
20 seconds of fuel left before they would have had to punch out and use
the ascent engine to get out of there.
